CONSTRUCTION OF RAILWAY-SLEEPERS- SPECIFICATION forming part of Letters Patent No. 770,349, dated September 20, 1904.

Application tiled January 18, 1904.

To all whom t may concern.-

Be it known that I, HARRY BYwA'rER, a citizen of the Unitedl States, residing at No. 799 Elston avenue, in the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in the Construction of Railway-Sleepers for the Support, Adjustment, and Attachment of the Rails Placed Thereon, of which the following is a specification.

My improvement relates to that class of railway-sleepers which are constructed of metal.

The object of my invention is to provide a railway-sleeper ofmetal, preferably of steel, easily and cheaply constructed, of several parts, arranged to provide a large base, a deep and secure anchorage in the road-bed, and thereby prevent lateral displacement; to provide ample footings for the rails, accurate and easy adjustment of the rails to the sleepers, and 'to prevent the spreading of the rails. I attain these objects by the construction and mechanism illustrated in the accompanying drawings, in which- Figure l is a plan view of the sleepers with the rails adjusted and secured thereto. Fig. 2 is a side elevation of a sleeper, showing the rails in section and part of sleeper cutaway to show the clamping mechanism. Fig. 3 is a cross-sectional view of one of the sleepers through the line 3 3, Fig. 2. y

The anglebars A form the body of the sleeper. Between these bars and near eachv end a jaw B is permanently aiiixed by bolts or rivets I). The piece forming this jaw extends under the base ofthe rail, forming, with the other parts, a solid support for the rail, as shown by the dotted lines in Fig. 2.

On the under side of the angle-bar A and at right angles thereto two angle-plates C are permanently aflixed, the horizontal sides of said angle-plates extending across both of the angle-bars A parallel with the base of the rails and in the direction of their length, and the vertical sides of said angle-plates extend down into the road-bed, thereby forming anchors for the sleepers, as shown in Figs. 2 and 3, thus preventing any lateral movement of the sleepers.

On each of the vertical sides of the angle- Serial No. 189,484. (No model.)

bars A two angle-plates D are permanently ailixed, Athe horizontal side E of each of said angle-plates extending parallel with the rails, for which they form supports. rFhe outside edges F of these plates are curved upward to receive and hold the outside edge of the base of the rails G. rIhe tops of the angle-bars A are also recessed at Hfto the level at the top of the angle-plates D. The outer vertical side I of these recesses, being in line with the outside edge of the rails Cr, holds the rail, togeth er with the parts F of the angle-plates D, from spreading on the sleepers.

Inside the rails and between the angle-bars A are two movable jaws J. These jaws are attached to the angle-bars A by pivotal pins K, on'which they are free to be partly rotated. The free ends of these jaws are adapted to rest on the inside oi' the base ot' the rails. Centrally located in each of these jaws is an aperture L, through which a bolt M is passed. Each bolt extends from its head and washer beneath the angle-bars A, between said bars and through the aperture L in the movable jaw J, and is threaded to receive a nut N, by which the jaw J is screwed down on lthe rail-base.

pin P, which isdriven through a slotQ in the threaded part of the bolt M and securely locks the nut when the jaw J is bolted down onto the rail.

When the sleeper is constructed as shown and in place on the road-bed ready to receive the rails, the Cotter-pin P is removed and the nut N is taken otf the bolt M, and the jaw J thus released is thrown back toward the center of the length of the sleeper and the rails are forced into place under the iixed jaw B and against the vertical side I of the recess H and curved edges F of the plates D. The movable jaw J is then thrown over onto the base of the rail G and made fast by the bolt M, nut N, and Cotter-pin P.

What I claim as my invention, and desire to secure by Letters Patent, isi

l. In a railroad-sleeper of the kind described, the combination comprising' a pair of angle-bars A forming the main body of the sleeper; a pair of jaws Bpermanently afiixed The top of the nut N is grooved, as shown at O, to receive a Cotter- IOO between the vertical sides of the bars A, a pair of angle-plates C permanently afiiXed on the under side of the bars A and at right angles to the length of said bars, the vertical sides of said angle-plates extending downward into the road-bed, four angle-plates D permanently afxed to the vertical sides of the bars A adapted to support the rails G; the outer edges F of said plates being raised to hold the outer edge of the base of the rails, a pair of adjustable jaws J pivotally secured to and between the Vertical sides of the bars A adapted to be secured upon and against the base of the rails by bolts and nuts, and bolts M adapted to pass between the bars A and through the jaws J and to receive and be fastened by nuts N, said bolts being provided with slots Q, in the threaded parts of said bolts, and vCotter-pins adapted to be driven through said slots and over said nuts, and into grooves in thetop of said nuts, substantially as described andfor the purposes specified.

2. A railroad-sleeper of the class described comprising the combination of a main body formed of two angle-bars A,a pair of fixed jaws B arranged between said bars and adapted to hold the outer base of the rails Gr, four angleplates aixed to the bars A as supports for the rails G, a pair of movable jaws J adjustably arranged between the bars A and adapted to engage and hold the inside base of the rails G and means for holding said jaws securely on said rails and said bars, substantially as described and for the purposes specified.

3. A railroad-sleeper of the class described comprising the combination of two angle-bars, a pair of iixed jaws adapted to receive and hold the outer base of the rail, a pair of adjustable jaws adapted to hold the inside base of the rails, and means for securing said adjustable jaws in the position required to hold said rails, substantially as described and for the purposes specified.
